CLAMP FOB DRAINS, TRAPS, 85c.

Application filed Almost 10, 1905, Serial No. 2755527. Renewed February21, 1907' To all whom it may concern: 7

Be it known that 1, WILLIAM J. lAvnoR', a citizen of the United States,residing in the my and county of Philadelphia, State oi Pennsylvania,have invented a new and useful (llhrnp for a Drain, Trap, &r-., of whichthe following is a specification.

My invention consists ol a clamp for a drain, trap, etc, the sameembodying a head, hooks thereon, a screw, freely fitted in said f r-3d,and a not with which said screw engages, provisior'iheing innde forpreventing the rotation of said head and not during the tightcningaction of said screw.

Figure 1 represents a side elevation of a clamp for a. drain, trap, etc.embodying my invention. Fig. 2 represents a. top or pla n view thereof.Fig. 3 represents a side elevation of a. modification. Fig. 4 representsat partial topor pln view and partial horizontal scetion thereof.

Similar letters ofrcferenc indicate corresponding parts in the figures.

Referring to thedrawingsi A designates a head i n the center of which isa verticallyorranged unthreadcd opening B to receive the shank of thescrew C.

On the ends of the head A are the hooks or hooked arms D which dependfrom said ends and are pivetallyconnected therewith by the bolts Ewhereby said hooks may swing from towards the shoulder F of the neck ofthe drain or trap G, it being noticed that the point of the screw isadopted to rest against the cup or cover H of said dmin or trap.

On the underside of the head A are inturned shoulders forming a recessor pocket I in communication with said opening 13 and in which is seatedthe nut K with the threads of which the shank of the screw C is adaptedto engage. This pocket I leaves the portion of the head A sboye the samereduced in thickness,

forming a necliugahist whose underside, said not K abuts and causes thebottom of the latter to be flush or comparatively fiushwith theunderside of thrhead,

so that said nut does not project below said head. which otherwise wouldcause an elongation of the arms D and of the screw C in order that theformer may properly roach thejshoulder F and the latter may passentirely through the head 'A and the nut K to hear against the top ofthe cap H.

It will be seen that the hook D may be thrown out and the head Airsplaced over the cup H, the hooks D then closing and engaging under theshoulder F. The screw C is then properly rotatcd whereby its point turnson and tightens against the cap ll, thus raising the hood and powerfullydrawing the hooks D against the shoulder F, Wlu-rchysnid cup II isfirmly clamped Specification of Letters Patent.

ratented Sept. 10, 1907 Serial No- 368,728.

upon the drain or trap and the joint of said cap and the neck of thedrain or trap is tightly closed. It is evident that when the screw isrotated in reverse order, the hooks are lowered, whereby they arerelieved of their hold on ihrshoulder F, so that they may be thrown outfrom the latter and the chimp rcniovod from its position. it will alsohe soon that the walls of the recess I prevent the nut K from turningand said nut obviates the employment of threads on the walls of theopening B, so that the shank oi the screw C is irce in said opening andthe rotation of said screw will not cause rotation of the head A andshifting oi the hooks D from their set position, while the chimp isbeing tightened.

In Figs. 3 and 4, I show hooks D us integral with the hood, in whichcase the clamp may be placed in posi tion by sliding it laterally overthe cap H, it being cvi- (lent that the hook D may also he placed inposition in the some manner if so desired. As the drain, trap, etc. maybe inconvenient of access and it may be difilcult to apply the clampthereto, I divide the head A in the longitudinal direction thereof,forming the sections L, M, as most plainly shown in Fig. 2, it beingnoticed that the bolts E from which the hooks D are suspended and thenuts N on said bolts serve to unite said sections, each section being acounterpart of the other section or matched as to the hall openings toreceive the screw C and recesses to receive the head of the hooks 1).

Either section may be placed in position over the cap H, the hooks beingplaced on the bolts E, then the other section may be located by sidemotion over said cap, its eyes receiving the ends of the bolts, when thenuts are applied and tightened, the head then being comparatively anintegral piece. Should either 1 1 crequired, the nuts N are unscrewed,and the bolts E withdrawn, whereby the sectional head may be lismemberedfor evident purposes.

Having thus described my invention, what I claim as new and desiresecure by Letters Patent, is:

1. In a clamp o! the character stated, a head having in its upperportion at the center thereoi, a reduced necii' and in its underportion,a pocket which extends from the lower edge of said head to thelower sideof said ncck'and a screw-engaging nut occupying said pocket and adaptedto hear against the underside of said neck and be engaged by the sidewalls of said pocket hush on its underside with the under edge of saidhead.

i. A clump of the character stated consisting of a head, engaging armsdepending from theenyls thereof, said 1 head having shoulders extendingln wardly from the under- 1 side of the center of said head formingthcycnt a reduc d neck und on interned pocket, said neck having thereinan l uutlirended opening which communicates with said pocket.
